Subject: nfsd41: use sv_max_mesg for forechannel max sizes
X-Git-Tag: v2.6.33-rc1~57^2~39
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ddc04fd4d5163aee9ebdb38a56c365b602e2b7b7;p=pandora-kernel.git

nfsd41: use sv_max_mesg for forechannel max sizes

ca_maxresponsesize and ca_maxrequest size include the RPC header.

sv_max_mesg is sv_max_payolad plus a page for overhead and is used in
svc_init_buffer to allocate server buffer space for both the request and reply.
Note that this means we can service an RPC compound that requires
ca_maxrequestsize (MAXWRITE) or ca_max_responsesize (MAXREAD) but that we do
not support an RPC compound that requires both ca_maxrequestsize and
ca_maxresponsesize.
